There is already a function to obtain the number of permutations possible
from a set (or list); but does anyone know of a function to obtain the
combinations?
For example, if the set is {a,b,c,d}, I want to list all 3-member
combinations possible, yielding {{a,b,c},{a,b,d},{a,c,d},{b,c,d}}.
Thanks in advance,
Erik Kulstad
